Make generated identifiers copyable

[advdv]

Currently generated identifiers have a 'j-' prefix but this my prevent users from copying the identifier.

Expected Behavior

when you double click on the identifier in the terminal it should select the whole identifiers

Actual Behavior

It only selects the identifier

Solution

• use a "_" between the j and the random string, this is not accepted by kubernetes though
• only show the prefix to the user, do not use it in the actual system
• alternative use "Jx4fda" as the identifier

It's not a problem on my linux, we need to test it on Windows

Also works with the j- prefix on Windows.
